2018 is end of life and 2019 will be released soon. Autoptimize 2.5 is not at that point yet, but I just pushed a version to GitHub which adds image lazy loading to Autoptimize;

The actual lazy-loading is implemented by the integrated lazysizes JS lazy loader which has a lot of options some of which I will experiment with and bring to Autoptimize to the default improve user experience.

If you want you can download the beta (2.5.0-beta2) now from Github (disable 2.4.4 before activating the beta) and start using the new functionality immediately. And if you have feedback; shoot, I’ll be happy to take your remarks with me to bring AO 2.5 ready for release (I’m targeting March, but we’ll see).

Autoptimize by default excludes inline JS and jquery.js from optimization. Inline JS is excluded because it is a typical cache-buster (due to changing variables in it) and as inline JS often requires jQuery being available as a consequence that needs to be excluded as well. The result of this “safe default” however is that jquery.js is a render-blocking resource. So even if you’re doing “inline & defer CSS” your Start-Render time (or one of the variations thereof) will be sub-optimal.

Jonas, the smart guy behind criticalcss.com, proposed to embed inline JS that requires jQuery in a function that executes after the DomContentLoaded event. And so I created a small code snippet as a proof of concept which hooks into Autoptimize’s API and that seems to work just fine; The next step is having some cutting-edge Autoptimize users test this in the wild. You can view/ download the code from this gist and add it as a code snippet (or if you insist in your theme’s functions.php). Your feedback is more then welcome, I’m sure you know where to find me!

Maybe not as exciting as WordPress 5 or even Autoptimize, but for my birthday I released a new version of Async Javascript which can now be configured to not Async for logged on users or shop cart/ checkout:

Concerning the very short-notice release-announcement of WordPress 5.0 with Gutenberg for Dec 6th: I’m with Yoast;He has a great “should I update”-checklist and conclusion in this blogpost;

Is now the right time to update?

Can your site work with Gutenberg?

Do you need it?

So our advice boils down to: if you can wait, wait.

So if you have a busy end-of-year, if you’re not 100% sure your site will work with Gutenburg or if you don’t really need Gutenberg in the first place; wait (while WordPress 5.0 stabilizes with some minor releases).
